Modifier and Type | Method and Description |
---|---|
void |
applyDiff(byte[] diff,
int offset,
int length)
Applies a diff to an existing object.
|
byte[] |
getDiff()
Returns a diff and sets the dirty map to false
|
long |
getVersion()
For accuracy checking, a serialized attribute can contain a version number
This number increases as modifications are made to the data.
|
boolean |
isDiffable()
If this returns true, the map will extract the diff using getDiff()
Otherwise it will serialize the entire object.
|
boolean |
isDirty()
Has the object changed since last replication
and is not in a locked state
|
void |
lock()
Lock during serialization
|
void |
resetDiff()
Resets the current diff state and resets the dirty flag
|
void |
setOwner(java.lang.Object owner)
This method is called after the object has been
created on a remote map.
|
void |
setVersion(long version)
Forces a certain version to a replicated map entry
|
void |
unlock()
Unlock after serialization
|
boolean isDirty()
boolean isDiffable()
